HENRI HERNU, 0F MEUDON, FRANCE APPARATUS FOR PURIFYING AND TREATING GASES.

Specification of Letters Patent.

Patented Mar. 7, 1922.

Application filed July 2, 1920. Serial No. 893,673.

(GRANTED UNDER THE PROVISIONS OF THE ACT .0! MARCH '3, 1921, 41 STAT. I, 1313.)

To all whom it mag concern:

Bait known that I, HENRI HERNU, a citizen ofthe French Republic, residin at Meudon, Seine-et-Oise, in the French epublic, have invented new anduseful Apparatus for Purifying and Treating Gases, (forwhich I have filed an application in France Dec. 9, 1918, Patent No. 493,682,) of which the. following is a specification.

For this purpose the apparatus comprises a special turbine distributing water from a circular Well into wings, or blades of different sizes and staggered on a rotary disk in such a manner as to obtain a preliminary washing and an energetic scrubbing of the gas admitted to the apparatus.

The gas thus washed passes through an open workcage and then through a series of perforated disks which receive a rapid movement of rotation thereby projecting towards the periphery,under the action of 'for washing and the solid matters 01'' impurities contained in the as. 1 The invention is shown, y way of example in the annexed drawing, in which fying disk.

Figure 1 shows, in vertical section the complete purifier; Fig. 2 shows separately, in face view, the washing turbine; Fig. 3 1s a face view of one of the purifyi bine; Fig. 5 shows a modified form of .puri- As will be seen from the drawing, Fig. 1',

.the apparatus comprises a water-{supply pipe r A an a gas inlet pipe E. a The water suppl is. furnished by the tube v A- to the centre 0 a turbine B fitted with straight or curved blades D and formed with a circular well C serving the purpose of spreading the water uniformly in a c1r- After having passed around the turbine -B it passes from the periphery thereof into.

the periphery of a rotatin cage M havin on its outside a series 0 perforations 0 suitable .shape or longitudinal openings formed as-shown and being provided with a.. sjeries of radial bars connecting the two heads of. the cage-.ito form an'open work cage which can be lined with metal netting.

The jgas 'is'thereby partly purified byits centrifugal force, the water which has served disks; Fig. 4 shows, in face view, the" drying turpassage through the openings in this cage, the plain parts of which separate and throw out by centrifugal force the solid matters or liquids held in suspension.

The gas next passes through a central opening F in the casing and meets a series of perforated disks G whose perforations form radial elements H with or without a rim I as shown in Fig. 3 or they may take the form of circular holes of different size formed in the thickness of the metal. One of these disks forms a bowl J covering the other disks in such a manner that the gas which has a tendency to follow the easiest path to the opening K traverses the disks, while any suspended matter in the gas encounters the plain parts driven at high speed and is projected by centrifugal force to the periphery. The shape of the enveloping "bowl further facilities the ejection of separated matter while at the same time opposing the passage of the gas towards the periphery and so cause it to pass through the disks.

When it has. passed through the disks the gas passes into a second turbine L the rear. face of which has exhaust blades, and outlet passages, for completely drying the gas before distributing it to the apparatus which,

areito use it.

It isto be well understood that the shape,

. constructional details, materials anddimens'ions of the purifier may vary without de'-' parting from the nature of the invention.

Thus, for example, the perforations of the disks Gr may be. partly formed with; upturned lips so as to form bafiles either inclined or perpendicular to the disks; the number of disks can vary and the radial elements may be in the form of a helix.

Again, a certain number of the disks may be fast and-the others mobile with the object of varying the speed of the passage of the gas through the orifices to render the action of the dlSkS more efiioacious.

Finally, the same arrangement can be adopted for the cooling and'puri ing of water by. causing. it to be traversed y pure air instead of gas, or as a refrigerator and purifier for vehicles using poor or other gas.

I claim: A combined gas purifying, washing and vided into three compartments,-a s-mlet to the same, a rotary shaft journa ed cendrying apparatus consist ng in a casing di- I trally with the gas-inlet, a turbine wheel, having staggered blades, a circular well and an open face, mounted on said shaft close against the gas-inlet, 'an adjacently placed cage fast on said shaft and having an open-n work periphery and perforations in its rear face, a screening wal with central passage in the rear proximity to said cage, a spaced wall with central passage to form intermeintermediate chamber, an exhaust and drying drum fast on said shaft to the rear of said spaced wall, and a water-jet tube directed through the gas-inlet towards said circular well.

HENRI HERNU.
